BRAKE.

SPECIFICATION Application filed October 5, 1894.

,To all whom it may concern.-

Be it known that I, EDWARD SPENCER HALL, of the city, county, and State of New York, have invented a new and useful Improvement in Brakes, of which the following is a full specification.

My invention relates to brakes for bicycles, and consists in applying a band-brake to the crank or pedal shaft within the usual tube thereon joining the axle-journals by winding the same thereon in the shape of a coil. It may be made of flexible r semiflexible material in the form of a cord, wire, or band and is provided with means for drawing the coil to tighten the same on the shaft.

Figure 1 of the drawings is a side View of a bicycle, showing the crank-shaft and the brake attachment. Fig. 2 is an enlarged sectional view of part of the tubular frame of the apparatus, showing the crank-shaft with the brake and its connections; Fig. 3, a plan View of a portion of the tubular framework,

partly in section and taken on line 0000 of Fig. 2, showing crank-shaft and brake.

The-parts of a bicycle are well known, and the one chosen for illustration consists, chiefly, of a tubular framework, which carries all of the journals.

A carries the journals of the front wheel, B and 0 those of the rear wheel, while 0, E, and Filcarry and support the journals for the cranks aft.

H is the crank-shaft; h, the crank with its pedal. Around the crank-shaft I place the brake I, which consists of a coil of cord, wire, or band made of suitable material, and, if of metal, may be tempered to give it sufficient spring to enable it to return to normal when released. This cord or band maybe'coiled upon the shaft either single or double. As shown in the drawings it is double, and should be so wound upon the shaft that when tightened the tendency of the shaft to turn will assist in tightening the brake. The end or ends of the brake may be secured in any suitable manner. As shown in the drawings, they are passed through the walls of the surrounding tube and secured by the nuts or bolts '5. The other end may be looped and the loop connected to the chain or bar F, at the other end of which it is attached to one arm of a bell-crank lever i suitably pivoted within formingpart of Letters Patent No. 545,492, dated September 3, 1895.

Serial No. 624,966. (No model.)

the tube A, and to the other arm of this lever is attached a connecting rod or chain i which proceeds up through the tube and at its other stops the revolution of the shaft, and this,'

acting upon the sprocket-chain or cogged rod, stops the wheel with which it is connected. By this arrangement I effect an economy in construction and provide an effective arrangement for braking applied directly to the pedalshaft, which enables me to dispense with a wheel or pulley thereof.

What I claim, and desire to secure by Letters Patent, is

1. A brake for a bicycle consisting of-a wire or band, applied directly and coiled upon the pedal or crank-shaft in a direction corresponding with the motion of the same, and within the tube joining the journals of said crankshaft and suitably secured at one of its ends, in combination with means for drawing the coil and thereby tightening thesame upon the shaft.

2. A brake for a bicycle consisting of a wire, cord or band applied directly and coiled upon the pedal or crank shaft in a direction corresponding with the motion ofthe same, and within the tube joiningthe journals of said shaft and su'itablysecured at one end and provided at its other end with connections to the hand of the rider, whereby the same may be drawn and tightened, in combination with the rear wheel of the bicycle, and a sprocket chain connecting the axle of the same with the crank or pedal axle, substantially as described.

Signed at New York city, in the county of New York and State of New York, this 27th day of September, A. D. 1894.
